Server memory for Lenovo systems

This 64GB DDR5 module is built for Lenovo servers that require registered ECC memory. The 2Rx4 organisation and PC5-38400 rating match the original Lenovo part 4X71M22550. It targets administrators upgrading or repairing compatible platforms.

Registered ECC RDIMM form factor

The registered design adds a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel. ECC circuitry detects and corrects single-bit errors to protect data integrity. The standard RDIMM connector fits the DIMM slots on supported Lenovo motherboards.

64GB capacity at DDR5-4800 speed

Each module delivers 64GB at 4800 MT/s with a 2Rx4 rank structure. This density and speed combination determines whether the part satisfies a specific server configuration. Buyers needing lower capacities or different speeds must select an alternative module.

Questions about this item

Does the DDR5-4800 interface limit this RDIMM to 4800 MT/s in a server that supports higher speeds?

The module is rated at DDR5-4800 (PC5-38400); the memory controller will run it at up to 4800 MT/s even if the platform supports faster DDR5 grades.

Will the 2Rx4 registered DIMM fit in a standard 288-pin DDR5 RDIMM slot?

Yes, it uses the standard 288-pin DDR5 RDIMM form factor and requires a registered DIMM slot with ECC support.

Is there a specific slot population order when installing four of these 64 GB modules?

Follow the server manufacturer’s memory population guide; typically fill the first slot of each channel before adding a second rank to the same channel.
